Hello, when I fetch news using calibre and upload it to my 505 I find that it freezes when I open the file. I select the file and it says 'formatting' down the bottom of the screen, and there is a circle of arrows spinning around in the centre. Then after about 30 secs, it just resets itself. This happens for newspaper downloads, which tend to be larger, but not for smaller downloads, such as The Economist.
